Errors produced by teeny-cuda.

Variants

CudaNotAvailable

No CUDA-capable device/driver was found.

CudaError

A CUDA runtime/driver API call failed.

Fields

code: c_uint

The CUDA error code.

message: String

The human-readable message from cudaGetErrorString.

UnknownCapability(String)

A capability string didn’t match any known GPU architecture.

CStringError(NulError)

A Rust string contained an interior NUL byte and couldn’t convert to a C string.

NvptxCompileError

nvptxcompiler failed to compile PTX.

Fields

code: c_uint

The nvptxcompiler result code.

log: String

The compiler’s error log.

BufferOverflow

A source buffer had more elements than the destination buffer could hold.

Fields

src: usize

Number of elements in the source.

buf: usize

Capacity of the destination buffer.

InvalidOptions

A --options-style compiler options string (crate::compiler::options::Options::parse) was malformed.

Fields

input: String

The original, unparsed options string.

reason: String

Why parsing failed.

Implementations

impl Error

pub fn from_cuda_error(code: c_uint) -> Self

Builds a Error::CudaError from a raw CUDA error code, looking up its message via cudaGetErrorString.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
